Abstract
The present invention provides for metallic nanostructures or nanoburgers comprising a dielectric layer positioned between metallic layers and their use in metal enhanced emissions systems to enhance emissions from fluorophores, including intrinsic and extrinsic; luminophores; bioluminescent species and/or chemiluminescent species. The multilayer nanoburgers exhibit several distinctive properties including significantly enhanced intensity of emissions, decreased lifetime and increased photostability by simply varying the thickness of the dielectric layer while maintaining a constant thickness of the two metallic layers on opposite sides of the dielectric layer.
